I remember a time when CD ROM’s didn’t exist. The best thing out for data back up and storage was tape. When CD technology came out it laid the foundation for the ability to download PSP ROMs. Although at first the gaming units used CD’s and people didn’t realize you could copy them to the computer for use on the computer but a bunch of people put their heads together and started to make emulates that served as a software go between for the computer to emulate the gaming system functions using the keyboard. The download PSP ROMs weren’t far behind.
As emulators got better, less buggy, and the compression technologies made it easier to compress and send games over the internet more and more people started to see the concept for converting gaming system games from CD into other formats like the PSP or Playstation portable. It was only a matter of time before all Playstation games would become available through the ability to download PSP ROMs.
When you download PSP ROMs they can easily be stored on a memory stick which will mimic the cartridge concept and you could play them on your PSP easily with absolutely no loss in game quality and resolution! You can download PSP ROMs all day and fit several on one memory stick. You can fit as many games as your memory stick will hold!
You can download PSP ROMs on many membership sites as well as by the game purchase sites. PSP gamers just love the convenience of the ability to download PSP ROMs on their computer and with the browser upgrade you can even download PSP ROMs directly to your PSP system from the web, and onto the memory stick (if it’s plugged into the unit).
Sony has been releasing some firmware upgrades (including the one with the browser upgrade in it) that are trying to circumvent the ability to play the emulated games, but luckily there are always people generating and creating hacked firmware upgrades that remove these limitations, thus you can continue to upgrade and still download PSP ROMs to use with your game.
